ISO 668 – Series 1 freight containers – Classification, dimensions and ratings is an ISO international standard which nominally classifies intermodal freight shipping containers, and standardizes their sizes, measurements and weight specifications.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes. Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal ...
By the end of 2013, high-cube 40 ft containers represented almost 50% of the world's maritime container fleet, according to Drewry's Container Census report. [ 47 ] About 90% of the world's containers are either nominal 20-foot (6.1 m) or 40-foot (12.2 m) long, [ 6 ] [ 48 ] although the United States and Canada also use longer units of 45 ft ...
the words, Pipe thread, the document number of the standard (e.g., ISO 7 or EN 10226) the symbol for the pipe thread type: G, external and internal parallel (ISO 228) R, external taper (ISO 7) Rp, internal parallel (ISO 7/1) Rc, internal taper (ISO 7) Rs, external parallel; the thread size; Threads are normally right-hand.
Steel pipe is often joined with threaded connections; tapered threads are cut into the end of the pipe, and sealant is applied in the form of thread-sealing compound or thread seal tape (also known as PTFE or Teflon tape) and the pipe is screwed into a threaded fitting with a pipe wrench. Threaded steel pipe is widely used in buildings to ...
Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths ...
A flat rack container is a shipping container with two end walls, but without side walls and roof. Some flat racks can also be equipped with pillars. Flat rack containers are also available as stake containers with and without end walls. [1] There are flat racks in the standard sizes 20′ or 40′, and also in the dimensions of high cube ...
